There's a lot in the Rogue FAQ so it's possible I missed the answers to these:
Mind you, I'm only level 10 so the answers may become apparent later but I'm too impatient and too excited about my rogue.
1. Can you pickpocket any mob or does it have to be humanoid?
2. What is stunlock? I've seen folks talk about it but don't see it on the talent trees.
3. Lockpicking. What is the purpose of opening locked doors? Just to level you skill or are there things to loot behind said doors?
Thank you in advance for your help.
